Publication number: 20120164399Abstract: A method for producing a colored or fluorescent substrate with a view to formation of a colored or fluorescent image including the formation. The method defines on a substrate of a colored or fluorescent matrix, pixels of at least two different colors, wherein each pixel forms a filter for a given color. At least one filter is an interferential filter or a filter obtained with colored or fluorescent particles.Type: ApplicationFiled: June 4, 2010Publication date: June 28, 2012Applicant: COMMISARIAT A L'ENERGIE ATOMIQUE ET AUX ENE ALTInventors: Alain-Marcel Rey, Chrystel Deguet, Laurent Frey, Francois Tardif

Publication number: 20120128086Abstract: An OFDM signal identification method in a received signal, wherein the received signal is sampled and cut off into blocks of P samples, each block being subjected to an inverse Fourier transform to obtain a plurality of symbols at a plurality of frequencies. For each frequency of the plurality, the kurtosis of the set of symbols thus obtained at this frequency is calculated, and then it is determined whether the kurtosis has a periodicity in frequency domain from kurtosis values calculated for the frequencies of the plurality, and the presence of an OFDM signal in the received signal is identified if the kurtosis has such a periodicity.Type: ApplicationFiled: April 22, 2010Publication date: May 24, 2012Applicant: COMMISARIAT A L'ENERGIE ATOMIQUE ET AUX ENE ALTInventors: Abdelaziz Bouzegzi, Philippe Ciblat, Pierre Jallon

Publication number: 20120100719Abstract: A method for determining a minimum tension compensation stress which will have a membrane of a thickness of less than or equal to one micrometer, secured to a frame, having, in the absence of any external stress, a desired deflection. The membrane can be made as planar as possible in absence of any external stress, and its thickness can be less than or equal to one micrometer.Type: ApplicationFiled: June 17, 2010Publication date: April 26, 2012Applicant: COMMISARIAT A L'ENERGIE ATOMIQUE ET AUX ENE ALTInventors: Christophe Constancias, Bernard Dalzotto, Frank Fournel, Philippe Michallon, Hubert Moriceau, Valerie Pouteau

Publication number: 20120094486Abstract: The method comprises affixing a thin sheet of crystal (8) onto metal (6) of same type as the sheet but amorphous or of small grain size, deposited in trenches of a substrate (1) to form interconnect lines for example. Annealing progressively imposes the crystalline structure of the sheet onto the lines. When the crystal (8) is removed, highly conductive crystalline lines are obtained since the grains thereof have been greatly enlarged.Type: ApplicationFiled: July 1, 2010Publication date: April 19, 2012Applicant: COMMISARIAT A L'ENERGIE ATOMIQUE ET AUX ENE ALTInventors: Cyril Cayron, Sylvain Maitrejean

Publication number: 20120061172Abstract: A coupling structure for a resonant microgyroscope produced on a substrate, wherein the coupling structure enables a vibratory movement provided by an excitation mechanism to be detected along a first axis, and enables it to be transmitted to seismic masses lying in a plane containing the first axis. The coupling structure includes a closed assembly of beams connected to the seismic masses so as to be anchored only to the seismic masses, wherein the assembly is positioned to detect the vibratory movement provided by the excitation mechanism, and to transmit it to the seismic masses along at least a second axis contained in the plane, wherein the coupling structure has no point of anchorage to the substrate.Type: ApplicationFiled: May 12, 2010Publication date: March 15, 2012Applicant: Commisariat A L'Energie Atomique ET Aux Ene AltInventor: Karim Yacine
